, Application filed November 9, 1905. Serial No. 286,618.

To all whom it may concern:

' Be it known that I, FRED BEEBE, a citizen of the United'States', and a resident of Lud- .ington, in the county of Mason and State of Michigan, have invented certain new and usefullmprovements in Grease-Cups; and I I do hereby declare that the following is a full,

clear, and exact description of the same," reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

thereby drawing the grease from the bearing and from the duct leading from the cup to the bearing, with the result that when the cup is refilled and the closure again inserted air is caught beneath the grease and'forced into the bearing, thereby preventing thegrease again entering until the air escapes, ofttinies causing the bearing to run hot.

The object of this invention is to provide a grease-cup from which the grease may be forced into the journal and which is adapted to prevent the grease from being retracted or wit drawn from the bearing when the closure 'is removed from the cup.

The invention consists in the matters hereinafter. described, and more fully pointed out and defined in the appended claims. In the drawings, Figure 1 is avertical centralsection of a grease-cup embodying my invention, showing parts in elevation. Fig. 2 is an enlarged sectlon taken on line 2 2 of Fig. lwith parts removed. Fig. 3 is a similar View, but showing aditferent adjustment of the parts. 4 is a section tanen on line 4 40f Fig. 2. F ig. 5 is a section taken on line 5 5 of Fig. 3.

As shown in the drawings, A represents the top of .a journal-bearing, which is tapped to receive the screw-threaded tubular stem at of the ease-cup A,, affording a duct to the cup A, as shown, is screw-threaded internally for the greater portion of its depth, and having threaded engagement therein is the externally-threaded plunger or closure B. EX- tending upwardly from said plunger and, as shown, integral therewith is a rod or shaft 1), provided with a longitudinal axial bore 6, opening at its lower end through the plunger into the cup and opening laterally adjacent its upper end through the aperture 1) in the side of said rod I). Said rod 1), as shown, is provided adjacent the upper end of the bore 1) with screw-threads 1)", adapted to receive thereon the centrally-apertured handle or lever C, by means of which the plunger is operated. Said handle is provided with a laterally-opening aperture 5), adapted when the handle is at the upper limit of its adjustment on the rod to register with the aperture 17 shown more clearly in Figs. 2 and 4, thereby ailording atmospheric communication with, the interior of the cup, and when said handle is at the lower limit of its adjustment to be out of register therewith, as shown in Figs. 3 and 5. The upper end I) of said rod 1) is reduced in size and screw-threaded and is provided with a set-nut C, adapted to be ad justed to permit said handle to have but a quarter-turn on the rod, and when it has reached the limit of its movement in either direction with respect to the rod the handle acts to rotate the plunger, movin it into or out of the cup, according to the irection of rotation.

The operation is as follows: Thecup having been filled with greaseD, the plunger is inserted, and the pressure exerted on the handle or lever C in screwing down the plunger rotates said handle sufficiently to close the aperture leading to the bore 1),

thereby preventing the escape of air from the cup. Said plunger may be adjusted in the cup to give any desired pressure on the grease to force it into the journal. When, however, it is desired to remove the plunger from the cup, the handle is permitted by the nut C to have a partial revolution 011 the rod b, which brings it into position for the aperture b to register with the aperture b'-, thereby permitting the air to enter the cup. Inasmuch as air can readily enter the cup from above the grease when the plunger is being retracted, there is no tendcncy'to draw the grease from the bearing and cause an aircushion beneath the same when the plunger 18 again lnserted.

' Obviouslyxthe cup may be constructed of closure and adapted when the closure is re- 3 5 any suitable material and in any preferred tracted to open the passage and when the form and size. closure is inserted to close the passage.
